Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Explosiveness
Administrative data
- Endpoint:
- explosive properties of explosives
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties

STATEMENT FOR JUSTIFICATION OF OMISSION OF STUDY
Name of substance: Benzene, ethenyl, ar–bromo derivs
Omitted study:A14: Explosive properties
Method:
The explosive properties were predicted based structural considerations rather than by formal testing using Method A14 of Council Regulation (EC) No 440/2008.Screening procedures represent an intelligent testing strategy (ITS) for explosive properties. In accordance with the Guidance on information requirements and chemical safety assessment, if ITS is applied correctly to the explosive properties endpoint, only substances for which it is suspected will give a positive result in one of the explosive properties tests need to be tested.
Procedure:
The structure of the substance was assessed for chemical groups that would imply explosive properties. Common examples of such groups areacetylenic compounds, metal acetylides, haloacetylene derivatives, diazo compounds, nitroso and nitro compounds, acyl or alkyl nitrites and nitrates, 1,2-epoxides, metal fulminates oraci-nitro salts, N-metal derivatives, N-nitroso and N-nitro compounds, N-azolium nitroimidates, azo compounds, arene diazoates, bis-arenediazo oxides and sulfides, triazines, high-nitrogen compounds, peroxy compounds, metal peroxides, peroxoacids salts, azides, arenediazonium oxides, diazonium sulfides and derivatives, arenediazo aryl sulfides, halogen oxide and N-halogen compounds.
Results:
A review of the structure suggests that there are no chemical groups present that would imply explosive properties.
Conclusions:
Based on the known chemical and physical properties of the substance and its chemical structure, a negative result is predicted for the A14 Explosive Properties test of Council Regulation (EC) No 440/2008.As such it is considered justified to omit the test.
